Wouldn't it be just typical of Satanists to pervert the sign language sign for "I Love You" and use it to covertly show other Satanists they are also in allegiance?

alumbrado, the sign itself or the ease with which you can do it yourself is not the issue; it's what it is USED for that is the issue. Just because I can easily do the sign myself of course doesn't make me or anyone else a Satanist.
BUT if I am in fact a Satanist, then the sign has a TOTALLY different meaning to ME and OTHER Satanists.

Especially showing the sign in public really should make people wonder...or are they so dumbed down that they dismiss even QUESTIONING such a display of suspected allegiance with Satan?
